<h3>Notes</h3>

When using the 
<a href="hotine_oblique_mercator.html">Hotine Oblique Mercator</a>
equations to evaluate this, I 
imagine the angle from rectified to skewed grid would be 90.<p>

I don't have information on what the OGC parameters should be.<p>

<h3>EPSG Notes</h3>

Can be accomodated by Oblique Mercator method (code 9815).<p>
